    The new CoroMill Plura cutter Sandvik Coromant offers optimized high-performance milling and grooving applications such as CFRP (Carbon Fiber Reinforced Composites) and GFRP (Glass Fiber Reinforced Composites).Production engineers, machine shop managers and operators will benefit the new milling cutter with patented troughs, especially in the aerospace industry where these materials are becoming more common, as well as automotive, motorized, wind power and shipbuilding industries The Solutions for specific composite materials are becoming an increasingly important factor for machine-shop workshops that seek improvement in quality,production cycle and cost. The abrasive content of many composites can cause problems such as fast tool wear, reduced cutting quality, increased temperature, unstable vibration and cutting conditions. Taking into account these challenges, the latest CoroMill Plura-based milling cutter Sandvik Coromant is designed to improve the processing of CFRP and GFRP on three-axis, four-axis and five-axis CNC machining centers, as well as gantry CNC machines and standalone arm systems Development.

    "The CoroMill Plura brand has a long history and proven throughout the industry, and by virtue of this latest generation of milling cutters and specially designed patented troughs, it can improve the air quality," said Aaron Howcroft, product manager for global composite materials at Sandvik Coromant.The processing capacity of aerospace composite parts, including fuselage, wing, stabilizing wing, beam, ribs, ribs,structures, floor beams, pillars and pressure tanks. Milling cutters provide high productivity, with the longest on the market In addition, they can also be a standard product for quick order, to facilitate the procurement team. "

    When milling and grooving the composite, the new milling cutter is mainly used for full radial feed and full slot milling. In some cases, you can also deploy finishing passes. The helical angle design ensures ideal sharpness and cutting edge strength, resulting in longer tool life and high quality surface, edge and groove surface quality. The series includes 3 knives: CoroMill Plura herringbone cutter, CoroMill Plura small spiral angle cutter and CoroMill Plura sawtooth cutter.

    CoroMill Plura herringtes with double 40 ° helix, especially for CFRP parts with glass fiber cladding. Due to the overlap between the chevrons, the milling cutter can perform well by reducing the vibration of the material in thin, flat materials.

    CoroMill Plura Small Helix (5) Milling Cutters are designed for smooth, burrless finishing requirements in CFRP workpieces with a large number of teeth designed to help quickly cut and coat heat. The right-hand and left-hand cutting edges are designed to be flexible in applications where the workpiece material is not stuck, such as weaker or damaged fixtures.

    Finally, the CoroMill Plura sawtooth has a large chip flute, so the material removal rate is very high. In addition, the groove type also provides a double cutting effect to reduce the stratification and vibration, and ultimately provide a tool to minimize the stress on the composite parts of the knife processing solutions.

    山特维克可乐满推出的全新CoroMill  Plura铣刀可在诸如CFRP (碳纤维增强复合材料) 和GFRP (玻璃纤维增强复合材料) 中提供优化的高性能铣削和开槽加工。生产工程师、机修车间经理和操作人员都将受益于这些拥有专利槽型的全新铣刀，尤其是在这些材料使用越来越普遍的航空航天行业，以及汽车、   摩托运动、风力发电与船舶等行业。

    对于在质量、生产周期和成本方面寻求改进的机加车间，专门用于特定复合材料加工的解决方案正在成为一个日益重要的因素。许多复合材料的磨料含量会导致诸如刀具磨损快、切削质量下降、温度升高、振动和切削工况不稳定等问题。考虑到这些挑战，山特维克可乐满的最新CoroMill Plura一代铣刀专为改善在三轴、四轴和五轴数控加工中心，以及龙门式数控机床和独立机械臂系统上的CFRP和GFRP加工而开发。

    山特维克可乐满的全球复合材料产品经理Aaron Howcroft说，“CoroMill Plura品牌历史悠久，且在整个行业中久经验证，凭借这种最新一代的铣刀和专门设计的专利槽型，可以提高航空航天复合材料零件的加工能力，其中包括机身、机翼、安定翼、梁、筋条、翼肋、框架结构、地板梁、支柱和压力舱。 铣刀可提供高生产率，拥有市场上最长的刀具寿命。此外，它们还可作为标准产品进行快速订购，为采购团队带来便利。”

    当对复合材料进行铣削和开槽操作时，全新铣刀主要用于全径向进给和满槽铣削。在某些情况下，还可以部署精加工走刀。螺旋角设计可确保理想的锋利度和切削刃强度，从而实现更长的刀具寿命以及高质量的表面、边缘和沟槽的表面质量。该系列包括3款刀具：CoroMill Plura人字形铣刀、CoroMill Plura小螺旋角铣刀和CoroMill Plura锯齿铣刀。

    CoroMill Plura人字形铣刀带有双40°螺旋，尤其适用于带有玻璃纤维覆层的CFRP零件。由于人字形容屑槽之间存在重叠，因此铣刀可通过降低材料振动在薄、扁平的材料中表现良好。

    CoroMill Plura小螺旋角 (5°) 铣刀专为CFRP工件中的光滑、无毛刺精加工要求而设计，带有大量的齿旨在帮助快速切削和涂层防热。右旋和左旋切削刃设计使其能够灵活的运用在工件材料装夹不稳定的场合，例如较弱或受损的夹具。

    最后，CoroMill Plura锯齿铣刀具有较大的容屑槽，因此材料去除率非常高。此外，槽型还提供了双重切削作用，以减少分层和振动，最终提供一个能够尽量减少复合材料零件上应力的刀加工解决方案。

    这3款CoroMill Plura铣刀在有或没有冷却液的情况下均可使用。
